"Of a certainty, yes. There is only one thing that I can do for France—hearten her soldiers for battle and victory."
Mark Twain
Personal Recollections of Joan of Arc
But take a morsel to eat now, a bit of the Elves' food; it may hearten you.'
J. R. R. Tolkien
The Return of the King
The longer the siege dragged on, the more it would hearten other recalcitrants, like Tytos Blackwood.
George R. R. Martin
A Feast for Crows
It cannot be otherwise, that is how we hearten ourselves.
Erich Maria Remarque
All Quiet on the Western Front
"Poor girl, you're worn out. It isn't like you to be forlorn. Stop a bit; I'll hearten you up in a jiffy."
Louisa May Alcott
Little Women
If they kill him, we're so much the better; if he kills them, we're none the worse." For the last time his dogs admired Hook, and devotedly they did his bidding. The boys, pretending to struggle, were pushed into the cabin and the door was closed on them. "Now, listen," cried Hook, and all listened. But not one dared to face the door. Yes, one, Wendy, who all this time had been bound to the mast. It was for neither a scream nor a crow that she was watching; it was for the reappearance of Peter. She had not long to wait. In the cabin he had found the thing for which he had gone in search: the key that would free the children of their manacles; and now they all stole forth, armed with such weapons as they could find. First signing to them to hide, Peter cut Wendy's bonds, and then nothing could have been easier than for them all to fly off together; but one thing barred the way, an oath, "Hook or me this time." So when he had freed Wendy, he whispered to her to conceal herself with the others, and himself took her place by the mast, her cloak around him so that he should pass for her. Then he took a great breath and crowed. To the pirates it was a voice crying that all the boys lay slain in the cabin; and they were panic-stricken. Hook tried to hearten them; but like the dogs he had made them they showed him their fangs, and he knew that if he took his eyes off them now they would leap at him. "Lads," he said, ready to cajole or strike as need be, but never quailing for an instant, "I've thought it out.
J. M. Barrie
Peter and Wendy
"Thy hate to Troy, is this the time to show? Ungrateful man! deserves not this thy care, Our troops to hearten, and our toils to share? Rise, or behold the conquering flames ascend, And all the Phrygian glories at an end."
Homer
